IMPACT OF LABORATORY INSTRUCTIONAL STRATEGY ON SECONDARY SCHOOL BIOLOGY STUDENTS' ACHIEVEMENT ON THE CONCEPT OF DIFFUSION IN MINNA METROPOLIS, NIGER STATE

Abstract

This research study examined the impact of Laboratory Instructional Strategy on secondary school biology students' achievement on the concept of difusion in Minna metropolis of Niger State. Two Hypotheses guided the study. Random sampling technique was used to assign the sampled schools to experimental and control groups. One hundred and sixty students (160) (80 from each School) were randomly selected and used for the study. The eperimental group students were taught the concept of diffusion using Laboratory Instructional Strategy while control group students were taught the same topic using conventional lecture method. The instrment used for data collection was Biology Achievement Test (BAT) questions consisting of 20-Multiple Choice Test Items on the concept of diffusion. It was found that Laboratory Instructional Strategy enhanced students' achievement on the concept of diffusion in biology. It was also found to be gender friendly. It was recommend that teachers should be encourage to employ the use of the strategy in teaching biology concepts and Niger State government should organize Professional Career Development programs for secondary school teachers in form of workshops, conferences and seminars in order to make them well equipped for efective utilization of Laboratory Instructional Strategy during teaching.
